Hi,

I have a Baxi 80 HE plus which firstly works fine for the hot water
system.

However for the central heating several times a week, the Central heating
does not come on as per timer controls. Although the lights on the timer
control light up as expected when the timer is set to swich the heating
on, the boiler does not fire.

However with several goes at switching the timer control on and off e.g.
clicking advance or boost and pressing the reset button on the boiler ,
the Central heating will eventually fire up ( 2 green lights) and stay on
until the timer control switches it off later in the evening.

There are no red fault lights showing on the boiler when it doesn't fire-
in fact when it doesn't fire up there are no green lights either showing
on the boiler.

The pressurised system is just over 1 bar.

Any ideas if this is more likely to be a timing control (Drayton Tempus 7)
which I could easily get replaced or a boiler problem ( lots of money)!

Thanks for any help

Chris

My pressure is 1.5 bar.
Worth a go?
